VEHICLE-TIRE.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed March 19, 1906. Serial No. 306,707.

To all whom it may concern:

Be i't known that I, JOSEPH ALLEND, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inVehicle-Tires, of which the following is a specification.-

The object of my invention is to provide a simple and eflicientspring-supported, resilient wheel tire for vehicles.

The invention consists in the novel construction and combinations ofparts hereinafter fully described and claimed.

In the drawingsz-Figure l is a sectional elevation of a portion of awheel provided with a tire embodying my invention. Fig. 2 is atransverse sectional view thereof as on the line 2-2 of Fig. 1. Fig. 3is a detail of one of the spring rings. Fig. 4 is a detail of the meansfor preventing lateral separation of the spring rings.

1 designates a wheel felly to which is secured a rim 3 having aperipheral channel 5 therein. Fitted within the channel 5 is the innerportion of a tire 4 of resilient material, the interior diameter of thetire 4 is greater than the diameter of the base of channel 5 of the rim3 to afford a space through which the tire may move toward and from thebase of the channel. Arranged Within the channel 5 and engaging the tire4 is a pair of spring rings 6 the diameter of which is greater than thediameter of the base of the channel, whereby the tire is maintainednormally away from said base. The rings 6 are supported away from thebase of the channel 5 at intervals around the tire by suitable blocks 7engaging the base of the channel 5 and the rings 6.

Extending centrally through the tire 4 is a ring 8 which is embraced bythe outer ends of radially arranged bolts 9 which extend through the rim3 and felly 1 and are provided on their inner ends with nuts 10 adaptedto engage the felly to hold the tire in place and retain it Within thechannel 5. These bolts 9 also extend through the blocks 7 and serve tomaintain them properly spaced around the tire.

In order to prevent lateral displacement of the spring rings 6 away fromeach other, I provide a series of links or bands l1 arranged atintervals around the tire -and as shown in detail in Fig. 4.

In order to permit the parts of the tire to be applied to or removedfrom the wheel, the tire 4 and rings 6 and 8 are cut or separated as onthe line l2 and the cut porl tions of the rings 6 and 8 are held inplace by tubes 13 and 14, respectively, which are secured to said ringsand one side of the cut portions thereof and thus enable the rings 6 and8 and tire 4 to be separated on the line 12 and sprung open to permitthe application of the tire to the wheel or its removal therefrom, asdesired. After the tire has been applied to the wheel and the nuts 10screwed up, the parts of the tire at the union line l2 are held firmlyin place.

During the travel of the wheel. the tire 4, between the blocks 7, ispermitted to move toward the base of the channel 5 against the action ofthe spring rings (l thus providing a very easy action for the vehicle inpassing over a road bed7 the spring rings G maintaining the tirenormally in the position shown in the drawings.

I claiml. The combination of a wheel rim having a peripheral channeltherein, a resilient tire within said channel and having an interiordiameterl greater than the diameter of the base of the channel, aretaining ring extending through the tire, radially arranged boltsengaged with said ring and extending through said rim to retain the tireWithin the channel, a pair of spring rings laterally of said bolts andof greater diameter than the diameter' of the base of the channel andengaging said tire, and means arranged at intervals around the tire to'prevent movement of said rings toward the base of the channel.

2. The combination of a wheel rim having a peripheral channel therein, aresilient tire within said channel and having an interior diametergreater than the diameter of the base of the channel, a retaining ringextending through the tire, radially arranged bolts engaged with saidring and extending through said rim to retain the tire within thechannel, a pair of spring rings arranged laterally of snid bolts and ofgreater diameter than the diameter of the base of the channel andengaging said tire, and blocks arranged at intervals within the channelto prevent move ment of said rings toward the base of the channel, saidblocks being held in place by said bolts.

In testimony whereof I aiix my signature in presence of two witnesses.

JOSEPH ALLEND.
